The plugin is a configurable switch which uses a Google Calendar as input. The plugin will check periodically if an 'eligible' event is active and if so will 'Trigger' the plugin. It can also be used to create events in Google Calendars
An 'eligible' event can be specified as any event, an event with a name that matches a keyword. As well events can be ignored e.g. all day event, events that match a keyword. Keywords can also match to part of an event description.
Scenes and other devices can be trigger either because the plugin is triggered or only when a specific event occurs.
